Would I be better off cutting these totes for 2 or 4 plants?

you can get away with 4 easy, depends on how often you want to fill your resivor honestly. i could grow two plants to flower with a 3 gallon resivor. right now i'm using it on 1 mother. could proboboyl actually flower 4 smaller plants with it, depends on how compact you want to go and if you can fill the resivor every day, heh.

i flower with a 18 gallon resivor, i had 6 plants on it at first, then i made a flood table to use with it and could probobly fit 9-12 max. right now i have two in it and with all the rootspace room they went from 8" tall when 12/12 was set to 3 feet 4 inches tall. that is more than triple in size, and it's not stretched badly.

welcome back russ

depends on how big the plants will be on harvest date. you could have two 4 foot plants in the 18gallons, or four 2-2.5 feet tall plants (or one 7-10 foot plant). Not sure why (probably read it somewhere), but i try for 2 gallons per foot of plant squared.
